How to do it...

We are going to create a simple application that creates three time points and compares them to each other.

1. In your  ~/test working directory, create a subdirectory called chrono.
2. Use your favorite text editor to create a chrono.cpp file in the chrono subdirectory.
3. Put the following code snippet into the file:

#include <iostream>#include <chrono>using namespace std::chrono_literals;int main() {  auto a = std::chrono::system_clock::now();  auto b = a + 1s;  auto c = a + 200ms;  std::cout << "a < b ? " << (a < b ? "yes" : "no") << std::endl;  std::cout << "a < c ? " << (a < c ? "yes" : "no") << std::endl;  std::cout << "b < c ? " << (b < c ? "yes" : "no") << std::endl;  return 0;}

4. Create a CMakeLists.txt file containing build rules ...
